  1. 1. Intermodulation Distortion in Active and Passive Components

    Författare :Martin Mattsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Intermodulation distortion; hyperabrupt junction; polynomial model; passive intermodulation; nonlinear analysis; loaded-line phase shifter; varactor modeling;

    Sammanfattning : Wireless communication is growing rapidly, and the demand for higher data rate, low latency, and availability leads to a more complex infrastructure with new challenges. Multiple communication systems have to co-exist in a densely populated frequency-spectrum, where higher power levels and more sensitive receivers are required. LÄS MER
